The statements which describe carbon are options (a),(b),(e),and(f) i.e,atomic mass of ~ 12 amu, atomic number of 6, 6 protons, 6 neutrons, valency of 4.
In the periodic table, carbon is a chemical element. C is its symbol. Since the number of protons in the nucleus of an atom is determined by its atomic number, carbon has a nucleus with 6 protons. Additionally, since the number of electrons in a neutral atom is equal to the number of protons, the number of electrons in an atom of carbon is 6.
Carbon has a valency of four because it needs to gain or lose 4 electrons to achieve a stable electrical state. Carbon has an atomic mass of 12 a.m.u. The periodic table's group 14 contains carbon.
The complete question is:
